of America, residing at Chicopee Falls, in the county of Hampden and State'of Massachwsetts, have invented new and useful Improv-ements in Cover-Locking Devices for Cotton-1 following is a specification. A This invention relates to cotton-beaters and analogous machines, the'obje'ct ,being to pro! vide improved devices for preventing the frequent accidents by'which those who work on or about said'machines frequently havetheir hands and arms'y badly injured, and to that The above-'referred-to coverand'cyilinder end to provide improved devices for locking" ldciigzdevice's comprise kthe fllowing inthe cap or cover ofthebeater-eylinder case struuientalitiesV and operate as below described i; A bolt-holding base J is firmly seand coacting devices for locking the cover of the conduit-section o the case through which -cured on one of said bearings B of the-beatershaft 'Gfor other part of the machine u'ear one the beaten cottouisfdiscliarged orcarried.

je'nd of the 'beater-cylinder cover I, and on away from th'e'cylinder-case, and devices'for preventing the rotation of said cylinder when said oase is' a sliding bolt K, `parallel with said shaft. The end of said cover 1, Fig. 2, ad-

said covers' hall heffreef-tobe opened, and

' joining thev saidbolt-holding base J, has a whereby' provision is `also ru'adefor the free vbolt-hole a; ther-cinto receive theinner end of said bolt K, a coiled spring o on the latter,

between apart of said base J and a finger- .bar w, fixed on said bolt, serving to slide the the invention consists in the vpeculiar con- .latter and carryrone end thereof into. said bolt-hole when the cover is closed, and thus lock the same in a ciosed position, as shown in Fig. 1;.4 Saidnbolt K has a socket orrecess fn in theside thereof. (see Fig. 2) to receive the end of'a second bolt r, below described. A disk L, 4a section of which is shown in Fig. 1, is fixed 'on C and has one or more bolt-holes c in the side tliereot` adjoining the inner end of said slidin-gbolt K, and the latter, actuated the spring o, engages said disk and locksthe said shaft C against rotary movement when said Fig. 2 is av fbeater-cylinder cover I is open, as partially fragmentary perspective view showing parts shown in Fig. 2.,. lfThe devices hereinbefore of the cylinder-cover and of the case of the described asv cooperating with the beaterbeater and of the cover' of the cotton-conduit shaft Gand connected with said bolt-holding and a portion of the latter and illustrating base J, including the boltK and spring o, and more in d'etailthe construction of and man- 'the perforated disk L on said shaft, in conner of applying our safety devices to the 'nection with the beater-cover, form the subbeater and conduit covers. ject-matter of our pending 'application for a Referring to the drawings, A indicates the patent led April 21, 1899, and renewed July bodypart of thecaseof themachine in which 7,' 1899, and therefore are not specically conduit,v I `indicating the beater cylinder 'cover on said casebody A.

whereby said objects are attained, all as herein-af ter fully described., andmore particularly pointed ont in the claims. l

This invention is in the nature of an im-y proveinent upon the invention forming the subject-matter of our application now pending and covering ,the .broad subject-matter hereof. l ai' j In the drawings forming part of this speciication, Figure lis a perspective view of that part of a cottonfbeater containing the beater devices and of thecovered conduit connected therewith having our improved safety-cover'- through A H is the cover of said cottonsaid beater-shaft.

' B indicates one of the two bearings of' theses .I has a bracket m bolt i,

said bolt fr has its lower end formed to enter I allowing the shaft C to rotate. The lower land said two covers I-I and I of the said socket n in the side of said vbolt K and a finger-bar t thereon for retiring the same from said socket.v A coiled-springu is placed on said bolt 1f between a pin thereon bracket bolt in cover in a closed position, while its lower end engages said bolt K, while the latter locks said cover I in' a like locked position.

The operation of the above-described devices, in connection with the driving-sl1aft the machine of said covers K into the boltactuated b v the springe, and the opposite end of said boit'is clear of said disk L,

end of the bolt-r rests against the side of' said bolt K and is not now engaged in said socket n, the latter, now being, by the said v cover I. To open either of said covers now l requires .that the machine be stopped v by the usual means, afterwhich the. bolt K, by grasp# l ing the finger-bar @may be slid out of engagel disk L and in so sliding said Abolt K the said ysocket n in its side is 'brought opposite the end of 4 said lbolt r, mtting thc latter, actuated bysa'id springu, to slide out of engagement with the arm N on the cover H and permit the latter to be opened and at the same time, by the entrance Fig. 2" clearly illustrates the `last-described positions of said devices, and therefore while said two covers are free to be `or are opened the machine cannot be run.

Having thus described entk ot' the United States, is-

l. In. ak cotton-beater or analogous machine, the combination with a disk fixed on the shaft machine having bolt-holes therein, and

of the case of the machine, of two bolts, both simultaneously locking `said covers in closed positions While the machine may and one of said bolts when slid out of locking I engage the lock the firstnamed bolt 1n engagement with said disk', .substantially 'as described.
